FLUSHING APPARATUS FOR WATER-CLOSETS.

v Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed April 22, 1916. Serial No. 92,848.

To all whom it may concern: I

Be it known that 1, WILLIAM F. CONRAN, a citizen of the United States of Anierica. residing in the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Flushing Apparatus for Water-Closets, of which lowing is a specification.

The object of my invention is to provide a flushing apparatus in which the tank and. exposed portions of the piping and valves normally contain no water. In flushing apparatus of this character it is desirable to place the inlet or supply valve in a covered position to protect it from the cold. A second object of my invention is to arrange the supply valve and the flushing valve so that they will operate simultaneously, and further to arrange the valves and pipe connections so as to permit of quick inspection and repair of the valves without disturbing or removing the supply and flushing valve casings or the piping connecting them with the hopper and flushing tank. In carrying this latter object into effect I provide a pipe which serves both as a jacket for the water pipe which-connects the two valves and as a means of permitting removal and replacement of the moving parts without interference.

In the accompanying drawings Figure l is a view of the complete flushing apparatus embodying my invention. Fig. 2 is a central vertical section of the inlet or supply valve casing. Fig. 3 a central vertical section of the flushing valve and easing. Fig. 4 a central longitudinal section of the flushing valve. Fig. 5 a similar view of a modified form of flushing valve, and Fig. 6 is a plan view of the flushing valve showing relative position of the valve operating cams.

Referring'to Fig. 1 of the drawings, 1 is a hopper having a seat 2 secured to a seatiron having a forked cam lever 3 pivoted at 4 to a post projecting from the flushing valve casing 5. The flushing valve casing has three threaded openings, one being connected by piping 6 with water tank 7; the second by pipe jacket 8 with the supply valve casing 9, and the third for the connection to the hopper. The supply valve casing has three openings; one to which pipe 8 is threaded,-the second being for the water service. connection 10, and the third being 7 the folfor the drain connection 11 leading to the usual waste pipe or trap 12.

The supply valve casing shown in vertical section in Fig. 2, is in the form of an elongated tubular casing 9 having its lower end reduced in diameter and externally screwthreaded as shown at 13 to receive the cou pling of the water supply pipe 10; its upper end is enlarged and internally screwthreaded to receive pipe-jacket 8, and at a point about midway of the casing is the drain port 14 formed in a screw-threaded extension 15 to which is connected the drain pipe 11 as shown in Fig. 1. Within the casing 9 is formed the drain passage 16 leading from the upper end of the casing to the drain-port. The bore of the casing 9 is cylindrical, the lower end being of smaller diameter and terminating in the screwthreaded inlet end 13. Immediately above the inlet the inside diameter is increased to form a valve chamber 17 and valve seat 18.

The inlet or supply valve and the valve for controlling the drain port are formed in a single hollow cylindrical piece 19 having a circumferential groove 20 and port holes 21 in line with the drain port 14:. and inlet holes 22 immediately above the closed lower end of the tube. At this part of the piece 19 the diameter is reduced to form a shoulder against wh ch is placed a washer 23 of leather or other suitable material to form the inlet valve and which sets upon the seat 18. The end of piece 19 terminates in a feathered guide 24 which works in the inlet 13. The valve piece 19 has a smooth uniform outside diameter except at groove 20 and makes a close slidi g fit in the reduced bore of the casing 9 and is the pipe 25.

The flushing valve casing shown in vertical section in Fig. 3 has a central vertical bore within which is fitted a bushing 26, having an internal flange 27 at the center to form a seat for the flushing valve. and two ports 28 and 29 leading. respectively, to the hopper and tank. Ports 28 and 29 are maintained in proper position by seating the bushing on a shoulder 8 and by a pin 30 which holds the bushing against rotation. The top of the flushing valve casing is closed by a plate cap 31 secured by screws to the flange 32 with a layer of suitable packing material 33 between the plate and the flange. Plate 31 has a central screw-threaded packing chamber through which the valve stem carried by and receives the screw-threaded packing sleeve 3st on the .post on which the hopper seat is pivoted is shown at 35;

The flushing valve comprises a hollow stem 36, externally screw-threaded at both ends; a flanged internally threaded coupling 37, a valve washer 38 of any suitable material, and which makes a close fit within bushin 526; a metal washer 39 and a nut 40. The lower end of coupling 37 receives the upper end of pipe 25. Above the nut 40 the valve stem is perforated as shown at 41 and between the nut and the packing chamber the stem carries a spiral spring 42 whose function is to move the valve stem downward. The upper or exposed end of the valve stem 36 receives a lifting head 4l3, which may be of any desired form to engage with the forked cam 3 of the hopper seat.

It will now be noted that the inlet valve and flushing valve are mechanically con nected together by pipe '25 and that the flow of water is from the inlet 13 to the inlet valve chamber 17 i from chamber 17 through openings 22 to the interior of inlet valve 19; through pipe 25 to valve stem 36 and through the openings e1. In other words, the inlet and flushing valves are connected by or mounted on a common valve stem which is hollow and constitutes the water way between the two valves.

in Fig. 5 is shown a modification of the flushing valve of Figs, 3 and 4:, similar parts being indicated by the same reference numerals. In this form, instead of screwing stem 36 directly into the coupling member 37, the stem provided with a head l-l, and. male coupling member 45 is substituted for nut to, and this coupling member screws into coupling 3'? the washers 38 and 39 being clamped between the flanges of the coupling members. in this form stem 36 is flexibly connected with the valve to overcome binding of movable parts in case the two valve casings are not in proper alinement.

In setting up the flushing apparatus, the two valve casings are placed in their respective positions with the connecting pipe jacket 8 and other pipe connections completed, but without the valves, connecting pipes 25 and 36, bushing 26 and cap 31.

The inlet and flushing valves with their hollow stems and 36 are assembled before placing in position and when assembled are inserted through the flushing valve casing. the inlet valve passing through pipe jacket 8, and entering its casing; the position of the flushing valve on the hollow stem having been previously determined so that the flange of the coupling member 37 will not strike shoulder 83'" and insure the seating of washer 23 of the inlet valve on seat 18. Bushing 26, pin 30, spring 42, and cap 31,

are then placed in position; then the pack ing material is inserted and sleeve 34 screwed down. The seat is then hinged to post 35 and lifting head 43 is screwed on stem 36 and adjusted sothat the downward movement of the hopper seat will raise the valve stems and valves until the flushing valve seats againstflange 27. To withdraw the valves and cooperating parts from the casings all that is necessary is to remove the" screws which secure cap-plate 31, and then by taking hold of liftinghead 4:3, the valves, stems, spring, bushing and cap-plate are withdrawn; the parts including the cap-'- plate passing between the forks'of' cam l'ever 3.

The operation of the flushing apparatus will be readily understood from the foregoing description of the parts, and may be briefly stated as follows: In the position of the parts as shown in the drawings, which is the normal position, the inlet valve is closedshutting off the water supply'and the flushing valve is open. When in use, seat 2 isdepressed and cam lever 3 acting: on lifting head 4:3 moves valve; stems 36 and 25, seating theflushing valve against flange- 27, unseating the inlet valve, and movinggroove 20 and perforations 21 above drain port 14: which is now closed by the inlet valve body; Through the upward movement of the: valve members, spring 4:2 is compressed. Water now enters chamber 17 and, perforations 22 and passes through hollow. valve stem 25' and the iiushing valve, and out through the perforations n, and through the pipe 6 to the tank. When the pressure on the. hopper seat is removed, spring 42-will move the, valve members downward to the normal position I shown in the drawings, shutting off the wa- 1' ter supply, and opening the flushing; valve and drain port. The water now flows from the tank through the ports of bushing 26 and into the hopper with practically adirec-t flow. After the tank is empty the water remaining in the valve stem 25 above the line of the drain port, and whatever Water may lea-k around the flushing valve into the jacket 8 will now drain ofl' through perforations :21, passage 16, and drain pipe 11.
